Methods for inducing a population of T cells to proliferate by activating the population of T cells and stimulating an accessory molecule on the surface of the T cells with a ligand which binds the accessory molecule are described. T cell proliferation occurs in the absence of exogenous growth factors or accessory cells. T cell activation is accomplished by stimulating the T cell receptor (TCR) / CD3 complex or the CD2 surface protein. To induce proliferation of an activated population T cells, an accessory molecule on the surface of the T cells, such as CD28, is stimulated with a ligand which binds the accessory molecule. The T cell population expanded by the method of the invention can be genetically transduced and used for immunotherapy or can be used in methods of diagnosis.

The present invention relates to methods for the induction and a cell to enter the Islet 1+ (Isl1+) lineage and methods for expansion of cells of islet 1+ lineage. One aspect of the present invention relates to methods to induce a cell to enter the islet 1+ lineage, and more particularly to a method to induce a cell to enter a the Isl1+ lineage to become an Isl1+ progenitor that is capable of differentiating along multiple different lineages such as a endothelial lineage, a smooth muscle lineage or a cardiac lineage. In particular, one embodiment present invention relates to methods to induce a cell to enter the Isl1+ lineage by inhibiting a wnt signalling pathway in the cell. Another aspect of the present invention relates to methods to expand a cell of the Isl1+ lineage, such as a Isl1+ progenitor by activating a wnt signalling pathway in the Isl1+ progenitor. Another aspect of the present invention relates to use of cells of the isl1+ lineage in subjects for therapeutic and preventative treatment of cardiovascular diseases.

This application describes the cloning of p63, a gene at chromosome 3q27-29, that bears homology to the tumor suppressor p53. The p63 gene encodes at least six different isotypes. p63 was detected in a variety of human and mouse tissue and demonstrates remarkably divergent activities, such as the ability to transactivate p53 reporter genes and induce apoptosis. Isotopes of p63 lacking a transactivation domain act as dominant negatives towards the transactivation by p53 and p63.

Methods and compositions for restoring sensitivity to the antitumorigenic effects of antiestrogen therapy and / or cytotoxic therapy and inducing cell apoptosis are provided. Contacting tumor cells to GP88 antagonists (e.g., anti-GP88 antibodies, anti-GP88 antisense nucleic acids, GP88 siRNA, and small molecules) induces apoptosis and restores sensitivity to the antitumorigenic effects of antiestrogen therapy and cytotoxic therapy.

The present invention relates to compositions and methods for inducing cell death or stasis in cancer cells or other hyperproliferative cells using anti-EphA2 or anti-EphA4 antibodies conjugated to toxins.

The present invention relates to influenza vaccine formulations and vaccination regimes for immunising against influenza disease. In particular the invention relates to vaccine formulations comprising an oil-in-water emulsion adjuvant and optionally 3D-MPL, their use in medicine, in particular their use in augmenting immune responses to influenza antigens, and to methods of preparation, wherein the oil in water emulsion comprises a sterol, a metabolisable oil and an emulsifying agent.

Disclosed are methods of making a genetically modified immune cell for modifying a tumor microenvironment (TME) and methods of modifying a tumor microenvironment (TME). In some embodiments, the method can include delivering a first vector to an immune cell, wherein the first vector comprises a nucleic acid encoding a protein that induces T-cell proliferation, promotes persistence and activation of endogenous or adoptively transferred NK or T cells and / or induces production of an interleukin, an interferon, a PD-1 checkpoint binding protein, HMGB1, MyD88, a cytokine or a chemokine. Methods of modulating the suppression of the immune response in a tumor microenvironment, minimizing the proliferation of tumor and suppressive cells, and increasing the efficiency of an anti-cancer therapy, anti-infection therapy, antibacterial therapy, anti-viral therapy, or anti-tumoral therapy are also provided.

The present invention relates in part to nucleic acids encoding proteins, therapeutics comprising nucleic acids encoding proteins, methods for inducing cells to express proteins using nucleic acids, methods, kits and devices for transfecting, gene editing, and reprogramming cells, and cells, organisms, and therapeutics produced using these methods, kits, and devices. Methods and products for altering the DNA sequence of a cell are described, as are methods and products for inducing cells to express proteins using synthetic RNA molecules. Therapeutics comprising nucleic acids encoding gene-editing proteins are also described.

The present disclosure concerns LNA oligonucleotides having a (sub)sequence of the general formula 5′-(MeCx)(Tx)MeCxAsAstscscsastsgsgsMeCxAx(Gx)(c)-3′, and preferably of the general formula 5′-MeCxTxMeCxAsastscscsastsgsgsMeCxAxGxc-3′, wherein capital letters designate an LNA nucleotide analogue selected from β-D-oxy-LNA, β-D-thio-LNA, β-D-amino-LNA and α-L-oxy-LNA, small letters designate a deoxynucleotide, and underline designates either an LNA nucleotide analogue as defined above or a deoxynucleotide. Such LNA oligonucleotides exhibit surprisingly good properties with respect to inhibition of the expression of Survivin by means of an anti-sense mechanism, and thereby lead to reduction or inhibition of tumour development in vivo. The LNA oligonucleotides are superior to other LNA oligonucletides targeting Surviving mRNA measured by functional read outs such as apoptosis induction and proliferation inhibition, and is potent in down-regulating Survivin mRNA and protein in transfected cancer cell lines, and induce apoptosis in combination with Taxol superior compared to other LNA oligonucleotides.

Method of diagnosing in an individual recent exposure to an agent which is a pathogen, vaccine or any other moiety which induces a cellular response, said method comprising determining in vitro whether the T cells of the individual recognise a protein from said agent having a length of at least 30 amino acids, to a greater extent than one or more peptide epitopes from the agent, a greater extent of recognition of the protein indicating that the individual has recently been exposed to the agent.

The field of the present invention relates to genetically engineered fusion molecules, methods of making said fusion molecules, and uses thereof in anti-tumor immunotherapies. More specifically, the present invention relates to engineered fusion molecules comprising an antibody (Ab) which can target tumor cells (e.g., RITUXIN®), fused to one or more biologic moieties capable of inducing apoptosis in tumor cells, e.g., tumor necrosis factor super family (TNFSF) member ligands such as TNF-α, CD40L, CD95L (also “FasL / Apo-1L”) and TRAIL / Apo-2L. Importantly, the engineered fusion molecules of the present invention retain the death-inducing properties of the biologic moiety at optimum concentrations and with reduced systemic toxicities.
